Two things I forgot to mention. 1, you can use sand paper to clean up the rust. I used a Dremel with a wire wheel because that’s all that would fit in that small space. 2, if you were doing the outside of the body, obviously you’d want to wet sand afterward and buff the area with a polisher. But in my case, since rust wasn’t in a visible area, I wasn’t going for a perfect factory finish, but more for a solid layer of protection. With every project, you have to decide for yourself how much of your time you want to invest for the result you are going for.
THE dealer would rape ya to get that much paint. Just look at their $50 CAD touch up kit. That will scare ya away. Than again if it comes back you just wasted extra cash on OEM paint. So you used good judgement.
@@IvansBikesBmws there are paint shops that can mix the paint up for you for cheaper. I think i got 2 quarts for 50$ for my car and it mached ok, since my car is 13 years old the factory color looks a bit different.
Ivans Bikes And Bmws thanks because i live in Albany NY and we get snow and i do wash mine every time it snow i was worry i was going to get rust quickly. But his is 13 years old not bad. At all
At 6:04 you show a close-up of the rust, how it looked like. Just a friendly reminder for anyone doing this same type of work on a similar looking door: There's a plastic band straight under the "drainage" hole that goes all the way around the door. You can see it as the small bump that has rust next to it. There's rust underneath it and I do suggest removing it as far as the rust has come, because there's A LOT of rust underneath it. Just painting over it, as Justin did, will only temporarily help, the rust will be back after one year. Did the mistake on my car of leaving it there, same way Justin did, now I have to do all painting all over again. So yeah, summary, REMOVE THAT PLASTIC BAND, and get the rust outta there (unless you are planning on selling your car after the paintjob)
That plasticity band is called seam sealer, if you remove it you need to replace it with more seam sealer. This can be bought at a auto store. The rust is actually starting from inside the door sandwiched between the two outer door skin and inner door skin. The best way to fix this after your paint repair is stop the rust inside this sandwiched section from spreading farther. This can be done by using a cavity wax, or if your real cheap even motor oil. By dispensing it in the door bottom through the drain holes at the bottom of the door. I do work like this for a living.
I usually also put some thin oil for cavity protection inside that seeps into the seems between the panels where the water always sits. Take special care if you have a French car from psa - my Citroen c4 gp has so small drain holes that they clog up easy and when i was inspecting i think i found nearly half a liter of water in the front doors.
Beauty! Just washed, waxed, detailed, and then swore! All along my passenger inner sill… bubbled up paint…😢 This helps immensely to back up what my approach was going to be. AND tremclad black as well!✌️🤘
Good video, but do not "double dip " the brush in the Naval Jelly Rust Remover. The rust particles will activate the entire bottle rendering it useless.
Nice job. I personally would have felt happier by removing the entire door card and checking what has been happening on the inside of the door, just in case. How did the rust start in the first place? - blockages or rust spreading from elsewhere maybe?
From factory, BMW fills the door panels with an anti rust gel. Over time, heat and maintenance washes cause it to run out of the doors which can lead rust that's not usually visible as it is inside the panels. Just sharing some info 😎
Is that square opening at the bottom supposed to be a drain? I think part of my problem is I took off the window trim on this door a while ago and when I put it back, it never quite fit the same. I wonder if water is getting through there
@@justinbuice that's usually where they fill the panels with the gel. I guess it does kind of act as a drain. I'd check your vapor barriers and weather stripping as well if you are getting a lot of water in there. There's the square hole on the left side and a hole in the corner on the bottom right side of the door. Personally, I'd fill the right side hole with a filler of some type as it would seem that that's where the most water if any would get in at.
I have been a dealer tech for 4 decades and an ASE Master Tech since 1978. At least you are doing something to prolong your car and delay rust. Anyone reading this, water enters everywhere on a car, truck or SUV. The rubber on the outside of a window that moves, is the “Door outer belt mounding”. It even when new, allows water to run inside the door. I actually had a passengers front door that had 50 gallons of water. The customer heard noise, thought the door hinges were bad, but the door just weighed (1 gallon water = 8 lbs X amount of water plus door = real dam heavy) There are drain holes stamped into the skin, door fake or both and leafs are the main reason they clog up. Behind the front wheel, leafs are washed down behind the plastic inner fender panel, gather and hold moisture to start rust on that skinny little piece of metal fenders. The drain holes are shaped like a flat blade screwdriver. A bent metal coat hanger, wire or compressed air can ensure they are open. Plastic fasteners are common but in or out, carefully get behind it, pull it out and use compressed air or a garden hose to clean it out. Check all from front to rear. On the front center, the welded steel holds the A/C condenser and radiator (Called Radiator Support /Core support) but it has drain holes in these areas as well. A company called “Eastwood” sells an inner frame rust coating. It provides a reusable hose and screws onto their spray can. Follow all instructions but tapping newspapers down to catch drips or runs is recommended. This is not an “Isocyanate” that requires breathing gear. If you keep your vehicles longer, sell it to your children or perhaps give to a grandchild, the vehicle will last longer and look better. Paint and body work is hard and expensive, but add rust, the sky is the limit. This is maintenance you can do. Rock chips on a metal hood look bad, but water starts rust underneath the paint. I have seen it spider-web out 5-6 inches under great looking paint. Hope this helps you help yourself. A quote found in the Bible.

Out takes at the end was funny🤣🤣🤣👊🏽✌🏽 Funny thing is i was washing my car today and saw a spot under the door of my Bmw 330e 2016 with rain marks at the bottom of the doors and thought I'd better clean that just incase it starts rusting. It's a good routine to have cleaning all the door shuts properly including boot and bonnet or trunk and hood. Justin your video's are always so intuitive and helpful. Thanks from London England. 🙏👊🏽👊🏽👊🏽👊🏽✌🏽👌🏽
Most rust comes from the inside of the door. Best to use Fluid Film application in the inside of the door at the bottom seam. Especially in areas of heavy road salt. Nice Job.
I would highly recommend you pick up a can of Fluid Film and spray the insides of the door with it. It is a rust proofing and will help prevent this. Only about 10 bucks for a aerosol can.
Hey this is off topic but piece of advice is, check your u joints on your front drive shaft. Mines went out around 125,xxx and BMW made them non serviceable which means you need to replace the entire drive shaft. By bmw the part is about 800 dollars but i ordered myself one from dorman which costed me 350 with replacement bolts. Its an easy job you can do at home so you dont need to speen thousands of dollars at the dealership
I have the same thing on the driver's door on my car. I'll be doing this once it warms up a little bit. Sometimes I wonder how bad the rust is under the car with all the salt that they use in Minnesota. This car has so much plastic on the bottom that it's hard to tell. Thanks for the awesome DIY! Keep it up! Also, love the bloopers 😂
well there is a bigger problem that you saw on the outside. If you want to do a complete protection you need to take apart the interior part of the doors and spray inside the door cavity wax! - buy something expensive and good product. the wax will spill out on those door holes- let it dry there do not wipe it- it will offer extra protection. other things- always use the car paint ! it is way better than noname paints , and clear coats whould be applied at least 2 layers and very very thin layers.
Great informative video thanks for sharing. I'm wondering now how does it look like today since you did it earlier? Any pics or follow up video? thanks
I'm curious how your rust fix job has held up since this video. If you still have that car, that is lol. I'm thinking about trying this on my Acuras trunk rim. Great video!
Justin can you help me, I currently have a little rust just along the line connecting to the front door handle how can I smooth this out it’s ruining the look of my e90, it’s like s blotch in the middle of the aerodynamic line on the car ✌️
Tape up the drain holes. Put about 2oz of trans fluid inside the door and drive around then drain. The trans fluid will work it's way inside the pinch seem and will pervert rust from ever forming
thanks good tips, but one thing, your clear bottle don't shake up and down but shake circle way you are not suppose to ear the ball inside like that :) have a nice day.
Additional notes from me -Remove or replace weather stripping if needed. -If the rust is bubbling through, you're going to replace the metal, get a new door, or have a body shop handle it. Hot dish soap spray Fresh water spray (rinse) Dry properly Mask good paint (use trash bag for outside of door & cards) Grind/sand down rust to bare metal *Loctite Naval Jelly* -Brush on -Let sit for 10 minutes -Rinse off w/ water -Dry adequately *Rustoleum Rust Reformer* -Let sit in a bucket of warm water -Two coats -10 mins to dry *Dupli-color Perfect Match (Or OEM exact paint coat ordered from Manufacturer or dealership, etc) -Two coats -One coat of clearcoat
The inside of the bottom of the back door. Those words basically stacked on top of each other states that nobody would probably ever notice. Lol. Great job though 👏.
That rust will come back in year or two in worst condition, you didn’t clean it well, you should take off all of paint and that rubberised seal cos rust is under that too, there is the rust actually start. Under thst rubberised seal is two sheet of metals pressed together and water comes inside of the door and stay there and rust start between those two sheets and goes under that rubberised seal and spreads on paint too. You need to take a part door and clean inside, put rust remover and adter that clean again, outside clean all paint and rubberised seal to bare metal and clean all rust and put rust remover outside too and clean it (not with water inside or outside the door), with alcohol or some liquid for cleaning spray guns like nitro cleaner. After that put new primer for protection of rust rhen rubberised seal, and paint, inside you need to spray primer too on that place you work on, after primer dries, spray all door esp bottom of the door where two sheets connects with resin to protect those spot from water where sheets are connected. Thats the way you take care your doors and be sure rust will not be coming back after year or two.
I would like to mention that overall good tutorial on rust treatment but problem is that in that spot the rust is gonna come back with years. that's due to that this is double metal place. it actually wasn't rusting mostly from which place you treated but more of the place that is between these double metal. that's the biggest problems of rust treatment. you never can really cure the metal surface between these two metals. only way to really cure this part is to take the welding apart. remove the panel and then treat these surfaces. in most cases replace.
@@DJSparkyPlug I remember asking some driving teacher about that, he said it's common in Finland to be freezing,then next day it will rain and all snow will melt and next day freezing again, that ice is called "Musta jää" "Black snow", because you dont see it, its pretty impossible to drive in that ice :D I fell 2 times on my bike because of that ice and my speed wasnt even above 10Km/H :D
@@deno202 Yeah with bike it is really slippery, I fell many times during winter when I still drove bike. :D But I think for cars it would be better to use stud tires during winter rather than using so much salt even though it wears roads.
need to wash out the bottom of the inside of the doors with water, spray out with air and let dry then add some ATF down in the crack of the door, that will keep rust from forming for a long time.
rust coming up to next wash your car with double power, if you have rust on those elements, the all parts like door need replace to another with good condition, it is not possible to remove rust from it..
Pay thousands of dollars to a body shop? ... if your door goes to shit you can easily find another matching door that’s never seen winter for a few hundred.
A great guide on how not to do. By using brass brush you're not removing rust, just polishing it. Also, it is a really bad idea to put brush back into the original container or rust treating agent. You must prevent contamination of original product. Instead you must pour the agent into separate container and dispose what is left after you've finished, never put it back. At this moment I stopped watching the video
Are U an IT guy? What u've done is just for the facade. That rust is from underneath... between the two layers of metal that construct the door. You need to remove that mastic/putty from the factory, use some rust inhibitor and then paint. Also a must is to use a LOT of WAX into the door panels! This step is to avoid the water to get between the two layers of metals that construct the door.
It’s under the seam sealer. That needs to be removed completely and the rust eliminated from the skin to shell. Anything else is nothing more than a cosmetic fix.
This doesn't really fix anything as far as i'm concerned, the rust is still there, it's just under the body panel filler and under the paint you applied. Remember guys that the seam you see in doors aren't welds, it's silicone sealant. The body panels are merely point-welded together, so over time, road salt may dig underneath the sealant, which is what happened here.
That's the thing I dislike about living where salt & snow is common. Worrying about rusting my cars, great video.
Finally found the video i need. I only found paint chip repairs without rust removal or gigantic rust spots with holes, using bondo and everything.

need to wash out the bottom of the inside of the doors with water, spray out with air and let dry then add some ATF down in the crack of the door, that will keep rust from forming for a long time.
Nice video, as always! sadly we need to wait for another week for the next one :(
P.D: loved the bloopers
Good enough!
rust coming up to next wash your car with double power, if you have rust on those elements, the all parts like door need replace to another with good condition, it is not possible to remove rust from it..
nice
Ha, nice! You still have the glasses!

Not overkill at all I stress cover everything
Pay thousands of dollars to a body shop? ... if your door goes to shit you can easily find another matching door that’s never seen winter for a few hundred.
A great guide on how not to do. By using brass brush you're not removing rust, just polishing it. Also, it is a really bad idea to put brush back into the original container or rust treating agent. You must prevent contamination of original product. Instead you must pour the agent into separate container and dispose what is left after you've finished, never put it back. At this moment I stopped watching the video
Literally just watched two videos in a row that referenced Kirby...

Look inside the door...
Are U an IT guy? What u've done is just for the facade. That rust is from underneath... between the two layers of metal that construct the door. You need to remove that mastic/putty from the factory, use some rust inhibitor and then paint. Also a must is to use a LOT of WAX into the door panels! This step is to avoid the water to get between the two layers of metals that construct the door.
Nice fix but with this method it'll be back in about a year :)

DONT LET RUST RUIN YOUR CARRRRRR

It’s under the seam sealer. That needs to be removed completely and the rust eliminated from the skin to shell. Anything else is nothing more than a cosmetic fix.
This doesn't really fix anything as far as i'm concerned, the rust is still there, it's just under the body panel filler and under the paint you applied. Remember guys that the seam you see in doors aren't welds, it's silicone sealant. The body panels are merely point-welded together, so over time, road salt may dig underneath the sealant, which is what happened here.
